By Elliot Eton Early on my first morning in Gaborone, I arrived at the Botswana-Harvard AIDS Institute Partnership (BHP) Research Lab and met Dr. Simani Gaseitsiwe, the Deputy Research Director. The night before, I had again reviewed several recently published articles he had sent to me, all analyzing immune system-driven HIV adaptation. He helped me synthesize this material, and we began to consider hypotheses to test.
